16.1 Running gnatls

In normal mode, without additional option, gnatls produces a
four-column listing. Each line represents information for a specific
object. The first column gives the full path of the object, the second
column gives the name of the principal unit in this object, the third
column gives the status of the source and the fourth column gives the
full path of the source representing this unit.
Here is a simple example of use:

The first line can be interpreted as follows: the main unit which is
contained in
object file demo1.o is demo1, whose main source is in
demo1.adb. Furthermore, the version of the source used for the
compilation of demo1 has been modified (DIF). Each source file has a status
qualifier which can be:

OK (unchanged)

The version of the source file used for the compilation of the
specified unit corresponds exactly to the actual source file.

MOK (slightly modified)

The version of the source file used for the compilation of the
specified unit differs from the actual source file but not enough to
require recompilation. If you use gnatmake with the qualifier
-m (minimal recompilation), a file marked
MOK will not be recompiled.

DIF (modified)

No version of the source found on the path corresponds to the source
used to build this object.

??? (file not found)

No source file was found for this unit.

HID (hidden, unchanged version not first on PATH)

The version of the source that corresponds exactly to the source used
for compilation has been found on the path but it is hidden by another
version of the same source that has been modified.
